If your SaaS onboarding survives worker crashes, manual changes, and duplicate events, you're using something smarter than a retry queue. Here's how reconciliation loops work, why they differ from command-based workflows, and what a production implementation looks like in TypeScript.
Most production outages aren't caused by bad code. They're caused by workflows that forget what they were doing. Here's how durable execution gives your long-running processes a memory.
Retries are unavoidable in distributed systems, but unsafe retries cause duplicate charges and lost state. Here's how idempotency keys, the transactional outbox, and inbox tables keep a workflow correct under retries, crashes, and redelivery.
Static rate limits won't save you when latency spikes or retry storms hit. Here's how to build adaptive concurrency control that actually protects your services.
Most SaaS architecture articles stop at database multi-tenancy. This one goes further: how to split your platform into isolated cells, route tenants into them, control blast radius, and rebalance without downtime.
How to design idempotent APIs so users never get double-charged, double-booked, or double-notified, even when clients retry like crazy.
Learn how consumer-driven contract testing helps teams deploy microservices independently without brittle end-to-end tests. Practical guide with Pact examples and CI/CD integration.
Learn how to design and implement saga patterns for handling long-running, cross-service workflows in microservices. From orchestration vs choreography to idempotency and observability.
How to split a growing system into cells so a bad deploy or hotspot hurts only a small part of users instead of everyone.
How to split your system into 'think' (control) and 'do' (data) parts so you can move faster without risking your core traffic path.
